About this app

Bass Thing is a simple, focused, and fun approach to learning your bass fretboard.

Practice scales, chord tones, note names, ear training, and chord progressions— all personalized to your goals. Plus, use our unique hands-free mode to control the app without ever taking your hands off your bass.

LEARN SCALES
-----------------------------------------------------------------------------
Shuffle through scales across the fretboard. Choose which scale types and fret range to include, and shuffle anytime to see the next one.

LEARN CHORD TONES
-----------------------------------------------------------------------------
Shuffle through chords across the fretboard. Choose which chord types and fret range to include, and shuffle anytime to see the next one.

FIND NOTES BY NAME
-----------------------------------------------------------------------------
See a note name, then play it on your bass. Play the correct note and we’ll shuffle to the next one. Choose which fret range or strings to include, and reveal the note on the fretboard anytime if you get stuck.

FIND NOTES BY SOUND (EAR TRAINING)
-----------------------------------------------------------------------------
Hear a note, then play it back on your bass. Play the correct note and we'll shuffle to the next one — or we'll replay it automatically after a few missed attempts. Choose which frets or strings to include, and reveal the note on the fretboard anytime you get stuck.

LEARN CHORD PROGRESSIONS
-----------------------------------------------------------------------------
Hear and play along to common chord progressions in rock, pop, jazz and blues. Plus diatonic and chromatic circles of 4th or 5th, or random diatonic chords. Each shuffle picks a new key or progression. Choose which progressions to include or the length of the progression. A great way to learn comping or soloing!

PERSONALIZE FOR YOUR GOALS
-----------------------------------------------------------------------------
Every scale, chord, and note exercise can be tailored to your level and goals — pick the fretboard sections, strings, chord types, or scale types you want to focus on.

HANDS-FREE MODE
-----------------------------------------------------------------------------
Bass Thing's hands-free mode lets you control the app without ever taking your hands off your bass. Play the 5th fret harmonic on the G string to shuffle to the next chord or scale, or reveal the target note. This pitch sits outside the normal bass range, so it won't interfere with your exercises.

METRONOME
----------------------------------------
Practice timing and fretboard knowledge together with the built-in metronome — use it alongside any exercise, or run it on its own.

Built for bass players who want a simple, focused, and fun way to learn the fretboard.
